The turbulent time known as the Sengoku (Warring States) Period of Japan was the time period when the weapons of Ninjutsu were used the most. In this book Soke Hatsumi explains their uses and history.
This was one of Soke Hatsumi's first books (also known as the green book) published in 1978 and has been out of print for many years.
This material is very, very interesting on the history of Togakure Ryu, obscure weapons and the warring states of Japan.
